UNITED STATES PATENT OFFICE.

HARRY L. JOHNSON, 0F BATTLE CREEK, MICHIGAN, ASSIGNOR TO JOHNSON AUTO- MATIC SEALER COMPANY, LTD., OF BATTLE CREEK, MICHIGAN.

CARTON-SEALING MACHINE.

To all whom it may concern:

Be it known that I, HARRY L. JOHNSON, a citizen of the United States, residing at the city of Battle Creek, in the county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Carton-Sealing Machines, of which the following is a specification.

This invention relates to improvements in carton sealing machines.

My invention relates particularly to conveyers for carton sealing machines of the type shown in my application for Letters Patent filed August 4, 1908, Serial No. 446,893, of which application this application is a division.

The main object of this invention is: to provide in a carton sealing machine an improved conveyer mechanism by means of which the cartons are effectively supported and carried along to be acted upon by the sealing mechanism.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A. structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a plan view of a carton sealing machine embodying the features of my invention, portions of the feed and delivery devices being broken away and the glue receptacle shown in Fig. 2 being omitted. Fig. 2 is a detail vertical longitudinal section taken on a line corresponding to line 22 of Fig. 1. Fig. 3 is an enlarged detail vertical section taken on a line corresponding to line 33 of Fig. 2, showing the details of the conveyer and its support. Fig. 4c is a detail vertical section taken on a line corresponding to line 4.-t of Fig. 3, showing the details of the conveyer flights.

In the drawings, similar reference numerals refer to similar parts throughout the several views.

Referring to the drawing, the frame 1 of my improved carton sealing machine is pref- Specification of Letters Patent.

Patented Feb. 11,1913.

Divided and this application filed January erably rectangular in general form, it being preferably made up of suitable longitudinal rails connected by vertical and horizontal cross pieces. I preferably support this frame in an elevated position by means of legs as 2. The mechanism is largely an ranged and supported within this frame and consists of the conveyer for carrying the cartons through the flap folding and sealing mechanism. Such seallng mechanism 1s preferably like that illustrated in my application for patent before referred to. The sealing mechanism is illustrated and will be described herein only in suflicient detail to show the operative relation of the parts.

My improved conveyer comprises a propelling chain which is generally designated by the numeral 3 and which is preferably made up of the links 4 and 5, connected by suitable pivots 6. On the links 4 I mount the carton engaging carriers which preferably consist of the standards 7 having cross pieces 8 thereon. These standards are adjustably secured to the links by means of the angle shaped brackets 9. The attachment is effected by means of the securing screws 10 and the set screws 11. This propelling chain is carried by the sprocket wheels 12 and 13 arranged at the front and rear, respectively, of the machine.

The conveyer way 1s arranged above the propelling chain and preferably consists of the bottom pieces 14 between which the standards 7 of the carriers project when the carriers are in their engaging or operative position. The side pieces 15 are preferably located oppositely to the cross piece 8 on standards. The bottom pieces 14 project forwardly beyond the side pieces 15 at 14 to receive the cartons from the feed devices which will be hereinafter described. This conveyer is supported on the uprights 16 which are mounted on suitable cross pieces 17 on the main frame. (See Fig. 3). The upper reach of the propelling chain is supported between the sprocket wheels 12 and 13 by means of the ways 18, in which the rollers 19, carried by the links, are arranged to travel so that the carriers are held against verticalmovement when in engagement with the cartons. These rollers are preferably arranged in pairs so that they also prevent the tilting of the carriers While they are in engagement with or carrying the carton. The forward ends of the ways 18 are flared at 20 so that the rollers 19 readily pass into the same as they pass over the sprocket wheel 12. I thus secure a conveyer by which the cartons are carried forward to the machine in a manner which advances them positively while they are being acted upon by the flap sealing devices.

The sprocket wheel 13 is loosely mounted on the shaft 21 and is driven through a suitable driving connection, the details of which are not here illustrated.

The cartons are preferably delivered to the conveyer by means of an automatic feed which is preferably substantially the mechanism described in my application for Letters Patent filed April 14, 1908, Serial No. 426,994, for carton sealing machines and preferably consists of a pair of feed belts 22 arranged with their rear ends at each side of the forward end of the bottom of the conveyer way. The top or upper planes of the feed belts being substantially the same as the top of the bottom conveyer way, so that the cartons may be shifted laterally from the feed belts onto the way. The rear ends of the feed belts are supported by pulleys 23 mounted on the shaft 24, arranged transversely of the machine. As these belts may extend any desired distance from the machine and be arranged so as to receive the filled cartons from a carton filling machine, or the cartons may be placed thereon by hand, if desired, I do not illustrate the supplying or delivery mechanism herein. The feed belts are, however, preferably driven at a speed which exceeds somewhat the speed of the carton sealing conveyer. The object of this is to secure a full supply of the cartons to the sealing mechanism. That is, that the cartons may be delivered to the sealing mechanism as rapidly as required.

As the cartons are carried forward by the feed belts 22 they are engaged by the stops 25 and held thereby until the stops are tripped by the shifting mechanism. These stops are substantially the same as those illustrated in my application for patent re ferred to. To the rear of these stops I locate the laterally moving carton shifters which I designate generally by the numerals 26. The carton shifting mechanism is preferably that described in detail in my application for patent, above referred to, of which this is a division, and I do not enter into a detailed description thereof herein. These shifters are geared or connected so that their operation is properly timed with the conveyer mechanism. The driving mechanism shown being that of my application last referred to. As the cartons are shifted onto the conveyer and carried forward thereby the flaps are properly glued and folded. The mechanism for doing this is preferably that of my said application, consisting of the rear flap folder 27, front flap folder 28, flap retainers 29, which retain the front and rear flaps in their folded positions, the flap spreaders 80 which turn the side flaps out to position to receive the glue from the glue mechanism 31, side flap turners 32 beyond the glue mechanism-and the flap pressers 33 co-acting therewith. As before stated, this mechanism is shown only to 'show' the op erative relation thereof to the conveyer and therefore its details and the details of the further described herein. From the conveyer the cartons are passed to the delivery tails without departing from my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: i

1. The combination of a conveyer comprising a way having a bottom and sides, the forward end of the bottom projecting beyond said sides, the objects conveyed traveling upon said bottom; a propelling chain arranged below said way; carriers arranged on said chain to project through said bottom when in their operative position, the objects carried by said conveyer resting upon and being propelled along said bottom by said carriers, and means for feeding the objects to the said projecting end of said way bottom.

2. A conveyer comprising a way having a bottom on which the articles conveyed travel; a propelling chain arranged parallel with the bottom; carriers arranged on said chain to project above said way bottom when in operative position to engage the articles resting thereon, said articles being pushed along on said bottom by said carriers; supports for the chain links by which the carriers are carried; and ways for said supports coacting therewith to support the carriers against tilting movement while they are in their article engaging position, said carriers being mounted on said chain for ards being adjustably secured to said brackets, supporting rollers for the links by which said carriers are carried, and ways for said rollers, said rollers being arranged in pairs whereby said carriers are supported and held in an upright position.

4. The combination of a conveyer comprising a way having spaced bottom and side pieces, a propelling chain arranged below said way, carriers for said chain consisting of standards arranged to extend upwardly through said way bottom, cross pieces for said carrier standards arranged oppositely of said side pieces of said way, standard brackets on said chain, said standards being adjustably secured to said brackets, suppon'ting rollers for the links by which said carriers are carried, and ways for said rollers.

5. The combination of a conveyer comprising a way having spaced bottom and side pieces, a propelling chain arranged below said way, carriers for said chain consisting of standards arranged to extend upwardly through said way bottom, cross pieces for said carrier standards arranged oppositely of said side pieces of said way, and brackets for connecting said carrier standards to the links of said chain, said standards being adjustably secured to said brackets.

6. The combination of a conveyer comprising a way having spaced bottom and side pieces, a propelling chain arranged below said way, carriers for said chain consisting of standards arranged to extend upwardly through said way bottom, cross pieces for said carrier standards arranged oppositely of said side pieces of said way, and supporting rollers for the links by which said carriers are carried.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
